Abstract
The utility model relates to a logic button switch with a lamp for a lift hall door. Three input nand gates are used. The utility model is provided with three independent reset terminals and one optical isolation coupler output, and has the self-locking and storing function of a switch signal. The utility model is provided with two wiring terminals, one is a three-bit wiring terminal, and the other one is a four-bit wiring terminal. The high-speed matrix input of a control system for an input signal can be realized, and the arranging and combinatorial output of a reset signal can also be realized; accordingly, the purposes that the quantity of signal wires can be decreased, and the manufacture, the installation, the debugging and the maintenance are convenient are obtained.
Description
The utility model relates to hoistway door band lamp logic button switch, and it belongs to the operating mechanism class that is applicable to that object moves on the qualification position of its movement locus or other precalculated positions.
Existing hoistway door band button switch, processing to each switching signal amount, at least need take independent I/O passage of control system, when therefore being used for higher floor, the I/O passage of control system indispensability is many, and control signal wire quantity is big, and construction and maintenance be trouble and cost height all, has improvement necessary in fact.
The purpose of this utility model provides a kind of hoistway door push-button switch novel, the band logic function, to realize apparatus for controlling elevator the permutation and combination of Room door switch signal is handled, thereby significantly reduce the required I/O port number of apparatus for controlling elevator, reduce holding wire.
Hoistway door band lamp logic button switch of the present utility model contains button 1, spring 2, switch housing 3, light-emitting diode 4, wiring board 5 and binding post 6, and it is characterized in that: described light-emitting diode 4 is high brightness LEDs; Described line plate 5 is provided with Digital Logic integrated circuit 7, it is 33 input nand gates, two 3 input nand gates wherein constitute rest-set flip-flop, its set end R can be by push-button switch ground connection with turn-on transistor 8, driven for emitting lights diode 4 and open light isolating coupler 9, its reset terminal S links to each other with the output of the 3rd 3 input nand gates, and the input of the 3rd 3 input nand gates had both been useed the RESET input 10 as, can pass through grounding through resistance again; Described binding post 6 has two, and one is 3 terminals, and one is 4 terminals.
Below will the utility model is described in further detail by accompanying drawing.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is electrical schematic diagrams of the present utility model.
Among the figure, 1 button, 2 springs, 3 switch housings, 4 light-emitting diodes, 5 wiring boards, 6 binding posts, 7 Digital Logic integrated circuits, 8 triodes, 9 smooth isolating couplers, 10 the RESET input, 11 signal output parts.
As seen from the figure, in the rest-set flip-flop that constitutes by two 3 input nand gates, it when set end R is flat high level, but after pressing knob down switch ground connection, just transfer low level to, so its output is a high level, thereby make thereafter triode 8 conductings, driven for emitting lights diode 4 is bright, drive a single channel light isolating coupler 9 simultaneously, as a result apparatus for controlling elevator just can from signal output part 11 obtain the closed signal of crossing of button and with the logical circuit electrical isolation; The output of the 3rd 3 input nand gates in reset terminal S and the logical circuit directly links to each other, the input of this 3 input nand gate is a low level by grounding through resistance at ordinary times, but after 3 binding posts 6 connect high level, can make this input (useing the RESET input 10 as) become high level, its output has the low level signal of resetting output as a result, enter the S end, thereby make rest-set flip-flop reset.Like this, as long as push-button switch is pressed once, this signal will be remembered, light-emitting diode 4 is bright always, light isolating coupler 9 is conducting always also, apparatus for controlling elevator can be realized the matrix input of switching signal by the conducting always and the electrical isolation of light isolating coupler 9, thereby makes control system can finish M with the input of m road, the output of m road
2Individual external signal amount input.When elevator responds the push-button switch signal of certain floor and during in this layer stop, apparatus for controlling elevator is exported 3 high level signals simultaneously extinguishes light-emitting diode 4, so light isolating coupler 9 disconnects.Due to the operation characteristic of the electric Room, having only the Room to reach in the cab two band lamp instruction button outdoors at most at synchronization need reset, and gets 3 permutation and combination so control the output line from the n root, can get C
3Plant combination, so n root output control line just can be finished C
3The signal reset processing.
During concrete enforcement, Digital Logical Circuits 7 can be with CD4023 or 7410, push-button switch is made of hollow stainless steel button, spring and direct welding two contacts in the circuit board, the stainless steel button strikes out hollow form with the thick corrosion resistant plate of 0.5-1mm, last table has Δ v notch v or Arabic numerals, high brightness LED is welded in the circuit board and is encapsulated in the hollow stainless steel button, and binding post then is used for outer circuit and connects.Energized presses the button switch, and then light-emitting diode is bright, the signal output part conducting, and control system is obtained switch closure signals; And when the RESET input of circuit was high level entirely, light-emitting diode extinguished, and signal output part disconnects, and switch resets.
Apparatus for controlling elevator with one 19 floor is that example can obviously be found out the advantage of the utility model with respect to prior art.Need 55 of push-button switches this moment altogether.As using normal tape button switch, each 1 of each switch input, output line need 110 signal wire transmits signals altogether, and control system are handled these signals in requisition for 110 I/O passages; And adopt the utility model can finish the input of 64 button actions signals with 16 holding wires of 8 output of 8 inputs, get 3 permutation and combination from 8 outputs again and can do to reset processing to 56 button closure signal again, amount to like this as long as 24 I/O passages, 24 holding wires can be finished in 19 floors all elevator button Signal Processing, and this is just than 110 much less of former need.In addition, except that Room door button signal increased with floor, other control signals were constant substantially, and this just can realize elevator control program, mode of connection standardization, brings great convenience for manufacturing, installation, debugging and the maintenance of apparatus for controlling elevator.
